particularly valuable. Besides this valuable work of description 

 of species, etc., a most valuable table is given showing commer- 

 cially equivalent woods of the district by the generally accepted 

 common name in each division rendering the work of prime im- 

 portance from a commercial standpoint, and one of great value to 

 lumbermen in new districts and to architects and wood-users 

 generally. Of equal importance to wood-users will be the very 

 excellent lists of wood of the region known to be suitable for 

 special purposes enumerated as follows: exposed to salt water; 

 for ship and boat building, for woods in contact with the ground, 

 paving blocks, furniture and ornamental woods, tool handles, 

 boxes or packing cases, etc. 



Other useful tables are those showing weight and hardness of 

 the most important woods. Although a considerable number are 

 found to be heavy and hard, still there is noted a surprising 

 number of light and soft woods or moderately light and soft 

 woods, and when it comes to bulk and total weight in the district 

 the proportion of these is very large. 



The work is illustrated by nine plates showing cross-sections 

 of 108 of the most typical and important woods. These are on 

 a uniform magnification of five diameters that require only an 

 ordinary hand lens — so these, too, will prove valuable aids in 

 recognizing the woods. A complete bibliography and an accurate 

 index add to the value of the work. 



Dr. Foxworthy gives a short summary as to the source of the 

 supply of the woods and the possibilities of future production. In 

 this, he was too conservative, and by refraining from any definite 

 statement, other than stating that large amounts will be available 

 for export, does not give as adequate conception as he might of 

 the possibilities. 



Dr. Foxworthy in this work has not only made a valuable con- 

 tribution to the scientific and economic knowledge of the world's 

 timbers, bound to be of immense use in the immediate future, but 

 has presented a work which for its standard of excellence and 

 thoroughness will serve as a model for others to copy.
